Import A4 Copy Paper — Buy in Bulk from Supplier in China

Tianjin Gurui Co., Ltd. supplies A4 copy paper in 80 g/m² grammage, manufactured from 100% virgin wood pulp. The sheet size follows international A4 dimensions, with a basis weight of 80G/M², moisture content between 3.5% and 4.5%, and whiteness exceeding 92%. Thickness measures 103-110 micrometres, with surface roughness TS at 75-175 ml/min and BS at 100-200 ml/min. Bending stiffness exceeds 110 Mn in the machine direction and 50 Mn in the cross direction. Opacity is above 94%, brightness ranges 102-104%, and CIE whiteness sits at 148-152.

The paper uses entirely virgin wood fibre rather than recycled content, which preserves fibre length and ensures consistent print registration and feed reliability. Brightness at 102-104% indicates strong reflectance for crisp text contrast. The specified CIE whiteness of 148-152 falls within the premium office paper band, where higher values correlate with perceived cleanliness and colour reproduction accuracy. Cobb test values of 27-33 g/m² measure surface water absorption; lower figures indicate better ink hold-out and reduced feathering with liquid ink systems. The tight moisture specification of 3.5%-4.5% prevents curling or jamming in high-speed copiers and laser printers operating in climate-controlled environments.

This grade suits corporate offices, government procurement, educational institutions, and print shops running high-volume monochrome and colour output. The 500-sheet ream packaging with 5 or 8 reams per carton allows flexibility for buyers with varying storage constraints. Palletised or unpalletised delivery options accommodate different warehouse unloading capabilities. Buyers should confirm current minimum order quantities, available Incoterms, and lead times directly with Tianjin Gurui Co., Ltd., as these trade parameters are not stated in the listing materials.
